Two cross roads, each of width Sm, run at right angles through the

Ray Of Light [21]

Answer:

Rs 57750

Step-by-step explanation:

width =5 m

length of first parallel road 70 m

area of first road 70×5=350 sq.m

length of second road 45 m

area of second road =45×5=225 sq.m

area of the common part of cross road with 5 m width that lies at the

center of the park 5×5 = 225 sq.m

area of roads = area of first road +area of second cross road−common area

=(350+225)−25

=575−25

=550sqm

cost of the construction per sq.m =Rs.105

total cost =550×105=Rs 57750

Point b is between A and C. if AB =2x, BC =3x+1, and AC=21, find the length of BC

leonid [27]

Step-by-step explanation:

We are here given that a point B is between A and C . Also ,

Value of AB = 2x
Value of BC = 3x + 1
Value of AC = 21 .

And we would like to calculate the length of BC . For figure refer to the attachment. From figure we can see that ,

$\rm:\implies AC = AB + BC$

Substitute the respective values,

$\rm:\implies 21 = 2x + 3x + 1$

Add like terms ,

$\rm:\implies 21 = 5x +1$

Subtract 1 on both sides,

$\rm:\implies 21-1 = 5x$

Simplify,

$\rm:\implies 20=5x$

Divide both sides by 5,

$\rm:\implies \blue{ x = 4}$

Now consider ,

$\rm:\implies BC = 3x+1$

Plug in the value of x found above ,

$\rm:\implies BC= 3(4)+1$

Simplify,

$\rm:\implies BC = 12+1$

Add,

$\rm:\implies \underline{\boxed{\blue{\rm{ \quad BC \quad =\quad 13\quad }}}}$

And we are done !
